CVE-2026-3765 is a SQL injection vulnerability identified in the itsourcecode University Management System version 1.0, specifically within the /att_single_view.php file. The vulnerability arises from improper sanitization of the 'dt' parameter, which is susceptible to malicious SQL code injection. This flaw allows an unauthenticated remote attacker to manipulate SQL queries executed by the application, potentially leading to unauthorized data access, data modification, or disruption of database operations. The vulnerability does not require any privileges or user interaction, making it straightforward to exploit remotely. The CVSS 4.0 base score is 6.9, indicating a medium severity level, reflecting partial impact on confidentiality, integrity, and availability. Although no active exploitation has been reported, a public exploit exists, increasing the likelihood of future attacks. The vulnerability affects only version 1.0 of the product, which is used primarily in university environments to manage academic and administrative data. The lack of patches or official remediation guidance increases the urgency for organizations to implement protective measures. The attack vector is network-based, and the scope is limited to the vulnerable application instance, without affecting other components or systems directly. The vulnerability highlights the critical need for secure coding practices, especially input validation and use of parameterized queries in web applications handling sensitive educational data.

The impact of CVE-2026-3765 on organizations is significant, particularly for universities and educational institutions using the affected software. Successful exploitation can lead to unauthorized disclosure of sensitive student records, grades, attendance, and personal information, compromising confidentiality. Attackers may also alter or delete data, impacting data integrity and potentially disrupting academic operations. The availability of the system could be affected if attackers execute destructive SQL commands or cause database errors. Given the remote and unauthenticated nature of the exploit, attackers can launch attacks at scale, potentially leading to widespread data breaches. The presence of a public exploit increases the risk of opportunistic attacks by less skilled threat actors. Organizations may face regulatory and reputational damage if sensitive educational data is exposed. The vulnerability could also be leveraged as a foothold for further network intrusion if the compromised system is connected to broader institutional infrastructure. Overall, the threat poses a moderate to high risk to confidentiality and integrity, with a moderate risk to availability.

To mitigate CVE-2026-3765, organizations should immediately implement strict input validation on the 'dt' parameter in the /att_single_view.php file, ensuring that only expected data formats are accepted. Employing parameterized queries or prepared statements is critical to prevent SQL injection attacks. If source code modification is possible, refactor the vulnerable code to use secure database access methods. In the absence of an official patch, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'dt' parameter. Conduct thorough code reviews and penetration testing to identify and remediate similar injection points. Restrict database user privileges to the minimum necessary to limit the impact of any successful injection. Monitor logs for suspicious query patterns or repeated access attempts to the vulnerable endpoint. Educate developers on secure coding practices to prevent future vulnerabilities. Finally, plan for an upgrade or migration to a patched or more secure version of the University Management System when available.
